The Tiffen 85/0.3 ND Combination Filter
blends both an amber color conversion 85 and a 0.3 neutral density
filter. The ND filtration provides a 1 stop exposure reduction for
darkening the entire image in order to photograph with a wider aperture
or slower shutter speed than normally required. The 85 filtration covers
the entire filter plane and converts the color temperature to 3200K for
use with type A (tungsten) film.
This filter is made using ColorCore technology,
a process that involves laminating the filter substrate between 2
pieces of optical glass, grinding flat to a tolerance of 1/10,000th of
an inch, and then mounting to precision metal rings.
- Combination of both an amber color conversion 85 and a neutral density filter.
- 0.3 ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
- 85 filter converts the color temperature to 3200K, allowing you to use type A tungsten-balanced film in daylight situations.
